Carus
Responsible Chemistry. Innovative Solutions.
Since 1915, Carus has supported critical industries through American manufacturing, chemical expertise, and a long-standing commitment to responsible operations. What began as a family-owned company focused on industrial chemistry has evolved into a trusted partner supporting municipal water treatment, environmental remediation, air purification, and industrial manufacturing applications across North America. Today, Carus continues that legacy …
As utilities across the country work to address PFAS in drinking water, granular activated carbon (GAC) has become one of the most widely adopted treatment technologies. GAC is effective at adsorbing PFAS, but PFAS are not the only constituents competing for adsorption sites on the carbon. In many source waters, naturally occurring metals such as …
At Carus, our commitment to safety, quality, and reliable service extends far beyond the products we manufacture. It continues all the way to the moment those products arrive at our customers’ facilities. A key part of that promise is Alliance Transport—our wholly owned subsidiary and sister company to Carus LLC. Reliable Delivery for Critical Products …
Performance in corrosion control programs should be measured — not assumed. Municipal utilities across the United States rely on documented data when evaluating strategies to reduce metal release and support compliance with the EPA’s Lead and Copper Rule (LCR). As infrastructure modernization continues nationwide, treatment optimization remains an important component of comprehensive water quality management. …
Permanganate is widely used across municipal and industrial water treatment applications due to its strong oxidizing capabilities and proven performance in processes such as taste and odor control, iron and manganese removal, and remediation. At Carus, we offer CAIROX® potassium permanganate and CARUSOL® sodium permanganate for water treatment and RemOx® S ISCO reagent and RemOx® …
Ethylene oxide (EtO) plays a critical role in modern manufacturing, particularly in medical device sterilization, pharmaceutical production, and specialty chemical processes. Its effectiveness as a sterilant and chemical intermediate makes it difficult to replace in many applications. However, EtO is also a hazardous air pollutant, and increasing awareness of its health risks has intensified scrutiny …
Consider How It May Impact Your Corrosion Control Program Many water treatment facilities are currently evaluating changes to how they treat drinking water. These changes can be driven by a number of factors, including capital improvements, plant expansions, regulatory updates, or the addition of new treatment technologies, including systems designed to address PFAS. While PFAS …
When remediation teams encounter chlorinated solvent contamination in low-permeability soils like clay, standard approaches can quickly run into challenges. Traditional dig-and-haul strategies can become costly, especially when disposal fees and trucking add up. At a former maintenance facility in the Midwest, our remediation partner faced just that — high concentrations of trichloroethene (TCE) in cohesive …
When you’re dealing with a contaminated site that just won’t play by the rules, standard remediation approaches can fall short. Whether you’re facing multiple contaminants, tricky geologies, or long remediation timelines, going all-in on a single technology might not deliver the results you need. That’s where hybrid remediation strategies come into play—particularly the powerful combination …
When you’re tasked with mitigating air pollutants like ozone, carbon monoxide, VOCs, or ethylene oxide, choosing the right catalyst isn’t just a technical decision—it’s a regulatory, operational, and financial one. That’s where Carus’ CARULITE® catalyst solutions come in. With options tailored to specific pollutants, operating conditions, and substrate configurations, CARULITE products help streamline emissions control …
